The KF5INZ "Easy Digi" digital mode interface for sound card modes

Introducing the KF5INZ “EASY DIGI” digital mode interface assembly

No, we didn’t re-invent the wheel, we just made a convenient, single board, isolated, digital interface that works for almost all of the digital modes on HF and VHF/UHF. Works with DIGIPAN, FLDIGI, MTTY, MMSSTV and most all other sound card programs! Work PSK-31, PSK-63, RTTY, SSTV, NBEMS, plus many other modes on your HF or VHF/UHF rig. We build these daily in our home shop/shack.

We have sold over 50 of these interface boards and assemblies on EBAY in the past 2 months with 100% positive feedback from users. We have sold to Australia, Brazil, United Kingdom, Canada, and the U.S.A., all with great feedback. We are still listing on ebay so go to ebay and do a search for “EASY DIGI”, and look at our feedback.

Nothing new about this technology, it consists of two 600 ohm line transformers for audio input and output from your pc to your transceiver, and an opto-coupled push to talk circuit that works off of an RS-232 port on your computer.

• Transformer coupled audio eliminates ground loops and AC hum on your signal
• Opto Coupled push to talk circuit also eliminates ground loops and false triggering of your PTT lines.
• Very small size, only 2 1/16” x 1 3/8” x .625” high, can be incorporated inside of many radios, with only your RS-232 cable coming outside of the radio.
• Weighs less than 3 ounces.
• High quality FR-4 double sided, solder masked, silk screened, Printed Circuit Board.
• Compatible with most modern ham radio transceivers.
• If you wish to not use the serial port for PTT, you can just use the audio channels and key your radio via VOX operation.
• Compatible with most USB to Serial port adapters for use on laptops and other computers that do not have serial ports.
• 100% American made, nothing imported, high quality FR-4 double sided, plated through, solder masked, printed circuit board.

If you need a microphone connector, be sure to indicate what radio you want your interface for (for the complete unit). If your radio uses an RJ-45 mic connector then there is no additional charge or wait time. If your radio uses an odd microphone connector then you may have to wait a few days until we obtain the correct connector. If you do not wish to purchase the mic connector, we will provide a pig-tail with the wire colors and functions defined in an accompanying wiring diagram.

The “Easy Digi” pcb assembly is offered with 30 day warranty and the complete, fully wired and assembled version also carries a 30 day warranty. We will not be liable for consequential damages to you or your equipment due to mis-wiring or mis-use. Our warranty policy will be to repair or replace your interface at our option if returned to us prepaid within the 30 day period from date of purchase. Items which have been mis-used mis-wired will not be honored under warranty. Please see the included instruction sheet to determine correct wiring and current
/ voltage limitations. We will pay return shipping to you. Units that have been modified from their original intended use as sound card interfaces will not be honored under warranty.

We accept paypal, checks, and money orders. Shipments will be held until checks and money orders clear. We ship within 24 hrs of receipt of funds.

Please contact N5CEY or KF5INZ with order info and for paypal information (see our QRZ pages for email address).

EASY DIGI

Hi (1) I wish to use your gadget for my Kenwood TS 520SE digital modes ( is it possible??) (2) TS520SE does not have any RS232 port or for that matter any kind of port which can directly used to interface with computer (3) To use digital modes on TS520SE, I have to make use of Phone patch in and Headphone Jack Is it possible for you to study the problem and find a solution to make TS520SE work on all kinds of Digital modes including SSTV. What would be the cost + shipping charges to India - please consider that I have to bear extra cost in terms of shipping hence would appreciate if the equipment cost is bare minimum 73 VU2CDW

Hi, yes, you can use this interface with a kenwood ts-520SE. The RS-232 Cable connects to your computer, not your radio. You then connect a cable from the interface to the microphone connector on your radio, and an audio cable from the external speaker jack on your radio to the interface. Then two more audio cables from the interface to your computer. In your case I would recommend you purchase the complete unit with microphone connector, (34.95) plus the 13.95 shipping. This is a plug and play system which would have you on the air in 5 minutes on any sound card digital mode including rtty, msstv, psk, even cw using fldii. Thanks for your email.

Nice set up

This device looks like it could just about interface with anything. Nice job of putting it all together. Think I am going to mark your comments and get one of them from you for the radios I have here. 73 de John WA8LGM

We have just received our 2nd lot of 120 circuit boards - have sold 100 of these now.
We are now offering the interface's with or without a USB to RS-232 adapter. The adapters have been tested for compabibility with Windows XP, XP-PRO, VISTA, and Windows-7. Just go to Ebay ham radio category and search for EASY DIGI.
Thanks to all who have made this little interface a success so far.
